8 Introduction The symbols given in this standard can be used on technical drawings for welded components. Designrelated specifications, such as type, thickness, and length of weld, weld quality, surface treatment, filler material and testing specifications, can be indicated directly at the weld by means of the symbols given in this standard. The principals of this standard can be applied to brazed and soldered joints. Clarity may be improved by references to collective information in the drawings or references to additional design-related documents. Preparation for production may require detailed welding-related planning. The type of representation described in this standard can be used for this purpose and complemented by additional productionrelated information (e.g. welding position, welding process, WPS, weld preparation, preheating ). This information is often given in production-related documents, such as work schedules or welding procedure specifications (WPS). Technical drawings are intended to clearly and understandably illustrate design-related specifications. Welding-related drawings should be prepared and checked by specially trained personnel (see ISO 14731). This edition of ISO 2553 recognizes that there are two different approaches in the global market to designate the arrow side and other side on drawings, and allows for either to be used in isolation, to suit a particular market need. Application of either approach identifies a welding symbol in accordance with this International Standard. The approach in accordance with system A is based on ISO 2553:1992. The approach in accordance with system B is based upon standards used by Pacific Rim countries. v

9 Welding and allied processes Symbolic representation on drawings Welded joints 1 Scope This International Standard defines the rules to be applied for symbolic representation of welded joints on technical drawings. This may include information about the geometry, manufacture, quality and testing of the welds. The principles of this standard may also be applied to soldered and brazed joints. It is recognized that there are two different approaches in the global market to designate the arrow side and other side on drawings. In this Interational Standard: clauses, tables and figures which carry the suffix letter A are applicable only to the symbolic representation system based on a dual reference line; clauses, tables and figures which carry the suffix letter B are applicable only to the symbolic representation system based on a single reference line; clauses, tables and figures which do not have the suffix letter A or B are applicable to both systems. The symbols shown in this International Standard may be combined with other symbols used on technical drawings, for example to show surface finish requirements. An alternative designation method is presented which may be used to represent welded joints on drawings by specifying essential design information such as weld dimensions, quality level, etc. The joint preparation and welding process(es) are then determined by the production unit in order to meet the specified requirements. NOTE Examples given in this International Standard, including dimensions, are illustrative only and are intended to demonstrate the proper application of principles. They are not intended to represent good design practices, or to replace code or specification requirements. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
